To all whom it may concern:

Be it known that HARRY ject of the King'of Great Britain andIreland, residing at 188 Albion'str'eet,Grirnsby,

then;bincling the blockfsecurelyto the spin,-

Lincoln, England, has invented certain new and useful'lmprovenients in, Signaling Ap- I paratus for Vehicles, (for which he has filed Y the vehicle, may I p locked'in the desired position froma'control box or device situated near thehand oi the line an application inv Great Britain May 19, 1919, Serial No. 12,513) of which the followingis a specification. 1 V p r This invent'on relates to signaling apparatus for vehicles whichjmay be controlled by control n echanism'described in the spec fication of my Serial No. 334,742, A: I

The object of this invention is'to prov de means wherein signaling;indicators, 'aron the front and Qbacl; of

ran ed generally g be readily turn'ediand the driver or operator.

The invention W111 now be describedlwith reference tothe accompanying drawings in I i V inclined sides, this portion being that which which i cover rernoved. p 4 i ;.Fig. 5 is avertic'al section of the arrowsupporting box; Fig. 4 being asection'on AB looking to the left,.Fig. 6 being a similar I H i Fi 7 shows the device and, ndicators niounted on a car.

Referring first to'rthe indicators and'their.

supporting boxes as "shown inFig's. l'to the indicator in this case is'in the form of a hollow arrow constituted byabox 1 pie vided with aremovable cover 2 having an" carriesa coil spring 22 one end of which is opening in, theshape of an arrow cut out of it. This-opening can be covered by a electric-lamp -6-secured in the bottom of the box. Theb'ack of the box 1 and the r'e-' flector 5 may have small observation holes 7 to enable the driver to see whether the H wire is released to a degree corresponding arrow is properly illuminated.

jecting split lug 9,-fthe', whole being perfoj rated and screw threaded at 8 to receive the I FR MAN, a sub co-pending patent application Figurel is a front view of one of the, in-' dicator arrows, F g-2 being a vertical sec tion, and Fig. 31 a front new w th the section looking to the right-..

The other end of thisspindle is supported Specification of LettrslPatentq Patentd Sept, 20, 1.921, 2 Application filed November 10, 1920. 'Seria1'lNo. 42 3, 135.

in a cylindrical casing [11 having a'removablecover 12. Secured to the bottom of the casing 11 is a plate or ring 13 having four equally distant holes or slots 14 having in; clined or countersunk faces 14 for a purpose to be described. i

"On the'jspindle 10 is freely .inoiintedsav plate 15 having two oppositely arranged slots 15?,adapted to receive studs 16 project ingfroni the back of a plate 17 having a square opening 17 to receive the corresponding shaped portion lO fofthe spindle 10.

These studsfor the portion of their length, nearest totheplate 17 are conical or have is normally situated in the slots 1'5 as clearly shown in" Fig; 5. I V

A doublegrooved pulley block 19 is supported partlyon the end ofthespindle 10 andpartlybyits reduced end 19 engaging in a circular recess or 1101612? in the cover 12. The block 19 and plate 15 are connected by means of two rods or members 20, and are at such a distance apart as to allow the plate 17 to move back slightly along the spindle 10, against the pressure of a spring 21, one end of which is secured in the recess in the block 19, while its other end pressesv against the plat/e17;

One ofthe circular grooves in the block 19 secured to a rod 23 in the. groove and the other to'a-pin 2 1 secured to the casing 11, or if the spring isarranged in the groove in the cap 12, its out'er end will be pinned to the to the amount of wire released.

In the" other groove 'I arrange a short length'of chain 25 (Fig. 6) one end being secured to a rod 26 in the groove and the" other end passing out of the casing 11 11 secured thereto.

through a hole 11 and into a tubular guide The other end of the chain is connected by means of an adjusting screw 26 to the end of a Bowden wirel26 or similar device which passes to the control handle or wheel 27 which as hereinbefore' studs 14:, and cause the studs to be partially moved backward and out a of the lower portionof the slots 14' in the plate 13, which up to then had looked the studs andthereby the whole device within the casing against rotation. The studs now ride up upon the counpleting the unlocking of the device.

ing plate will be rotated to a quarter or a half revolution in an anticlockwise. directionor a quarter revolution ina clockwise direction in accordance with the movement of the Bowden wire. Owing to-the square portion 10 of the spindle, the] latter will also be rotated, and thus the indicator arrow will be turned through aquarter or a half revolution in I anticlockwise direction, or a quarter revolution in a clockwise d1rection.

Normally the arrow points upward indicating that the vehicle is going straight ahead,if turned to the drivers right'by the agency of spring .22 upon releaseof the Bowden wire through 90 so as to point horizontally to the right it indicates that the driver is about to turn to theoright, if

turned through 180 the arrow points downward,- indicating stopping or slowing up, while if turned to the drivers left by the agency of the Bowden wire26 through 90 it points 'horizontallyto the left indicating aleft hand turn is about to be made."

It will be seen that the interposition of theplate 17 with its studs, between the block 19 and the shaft 10 allows thepointer to be readily turned to any desired position by means of the Bowden wire control but the pointer cannot be turned by hand from the outside, since on any such attempt being -made the studs 16 will engage against the flat sides of the holes 14: in the plate 13, whereby any turning movement is prevented. When, however, 180 rotation of the arrow is effected through the agency of the plate 15 eithercby the Bowden wire 26 orby the coil spring 22, the studs 16 will engage with the next hole to come into register, but owing to the cam action of the in-' clined sides of the studs and of the plate 15,

be secured to any suitable part of the ves 7 derstood that when the arrows face in oppo- I Consequently, the block and studs carrythe studs willv be immediately disengaged again, so that the rotation is not interrupted. I In the drawings. the casing 11 is shown as supported on a U shaped bracket which can hicle. 7 It should be noted that there is no 'constructional difference between the front arrow box and the rear arrow box except'that their respective operating chains are se-- cured to the blocks 19 at points which are apart with regard to one another; 7

If the arrow boxes were turned so as to, both face in one direction the arrangement of the parts of each would be seen to be identical (except the points of fixation of the chains to the wheels)'-springs wound .the same way, and the chains-leading on the same way. 'If the arrows are now oper-@ ated by the control box it will be seenthat a turn can becmade in opposite directions c I f since the chain ofone is pulled while thatof' tersunk openings, of the slots ,14 thus comthe other is released. Henc it will be un v prising indicators mounted on spindles" at 9 5 the front and rear of the. vehicle, and operated from the control handle or wheel with in reach of the driver, so that on turning the control handle the indicators'will be corre spondinglymoved to the desired signaling position and a locking device fortheindicator spindle to prevent movement of'lthe indicator from one signaling position to another except by operation of the control device.
